i use pantene too, but for a long time i used one for "curls" or for "volume" or something, because i have kind of fine hair. i switch to a shampoo for straight hair (now i use "always smooth" pantene).
also bro, check this shit out, it's what i use for conditioner:

although yeah i have fine hair so maybe it works better for me than it would you, but they have other kinds other than "breakage defense". my hair is fine and used to break a lot (and you get those little half-hairs that stand up and look bad) but its much healthier now after using this stuff. maybe you should try the "frizz control" kind or something.
